Twyman-Green Interferometers

PhaseCam laser interferometers are the industry choice for measuring surface shape of large focal optics and aspheres, and for determining the quality of complex optical systems. 

Fizeau Interferometers

Fizeau interferometers are the workhorse of optical manufacturing because of their versatility for measuring flat and curved optical components. AccuFiz Fizeau interferometers produce accurate, repeatable interferometric measurements of surface shape, radius of curvature and transmitted wavefront quality. 

Optical Profilers

Optical profilers from 4D measure surface roughness and defects on smooth and supersmooth surfaces. 4D profilometer measurements are non-contact and immune to vibration. The NanoCam HD is extremely portable and perform in challenging environments. The 4D InSpec Surface Gauge is the first handheld, precision instrument for non-contact measurement of surface features and defects.

Software from 4D Technology

4D makes two software applications that can be used for developing your own analysis and data review:

  • 4Sight Focus Acquisition and Analysis Software for Interferometers and Profilometers. An industry-leading application for acquisition and data analysis of metrology results.

Upgrading 3rd Party Interferometers

Cost-effective upgrade kits to refurbish and enhance older temporal phase shifting laser interferometer systems. Available for interferometer systems from ADE Phase Shift, Buccini, WYKO®, Bruker, Kugler and Zygo®.
